I saw an episode of "Wild America" with Marty-something hosting.

They showed a racoon being attacked by a mountian lion.

That racoon instantly turned into a threshing machine, and in the blink of an eye, the mountiain lion was trying to get the hell away from the racoon, doing several 4-5 foot vertical leaps, and finally running a full speed to get away.

Pound for pound, there can't be many tougher animals.

Only one I've heard about, but never seen, is the wolverine. Heard a story from an old timer about an encounter between a wolverine and a brown bear. The bear lost the fight.
